Abstract: A method for transmitting signaling and control information for wavelength-division multiplex networks for optical, fiber-bound information transfer in digitized form, the signaling and control information being transmitted via the same optical channel, particularly with the same wavelength, as the useful information, but being encoded and decoded independently thereof, with the result that the control and signaling information can also be accessed independently of the useful information. The use of a time-division multiplex method allowing the different encoding of useful information and control information makes it possible considerably to reduce the technical complexity of passive optical network elements with regard to the routing of the signaling and control information. This method permits the simple, low-cost and transparent transmission of signaling and control information in the optical WDM network.

Abstract: A method for reducing bandwidth when transmitting data between a sending terminal and a receiving terminal over a voice connection path using a digital data network. The coding of user information is converted within the digital data network between data transmission in the voice connection path and data transmission in the digital data network so that the user information is transmitted on one section of the digital data network via the coded voice connection path and the user information is transmitted on another section of the digital data network using a method suitable for the digital data network.

Abstract: The present invention provides a method for providing locality information in a plurality of switched networks of different network types. The method includes transmitting network-specific information of a caller via a signaling protocol of a service logic located on a service platform. Using the transmitted network-specific information of the caller, a current locality information of the caller is determined by a network-specific location information server. The current locality information is provided in a uniform manner outside of the signaling protocol.

Abstract: The invention relates to a method for providing and processing locality information in switched networks (1 to 3). The aim of the invention is to overcome the problem of conventional switching methods of connections, whereby said methods depend on the origins. A uniform method which is compatible with conventional network architectures is provided for providing information on locations. The existing signalling protocols which are partially standardised do not require modifications. Different networks (1 to 3) can be interconnected by means of different methods for determining co-ordinates and in a particularly simple manner and a service extending beyond one network is possible by virtue of the selected architecture and the separation during transmission of signalling information and geographic co-ordinates.
